.Application inea May 1e,

T0 all whom it may concern."

Be itiknown that L'Axnii M. `l\]k`ni.soiv.a citizen of the UnitedStates, residing at Chicago, inthe county of Cook and State of Illinois, havel invented a newand useful Improvement kin Tank Cars, yoit' which lthe s followingy is a `speciiication.

My invention relates totank carswhich, n in accordance with common practice, arey provided with ymeans for A preventing n displacement of .the tank portions y thereof` lengthwise of thecars, as for examplerinv pre-y venting the displacement referred tol of the the form of anchorages "which,l while tank portions on the under frames, permit them to expand land contracty under variaerted longitudinally,y of the car` structural The cradlemembers arecommonly formed with cradle slabbing of wood, assuch material has proven to be the most suitable` l tank cars of the so-called center anchorage one to be used. flsvlfood,y however, `shrinks and thus draws away Jfrom the tank portions of the cars, with the result that the means, preventing displacement of the tank portions lengthwise yof the cars, are caused tobe subjected to stresses, due tothe weight y of the tank portions imposed thereon, which it is desired be avoided. n

`It is my primary object to provide a str'uc, ture of the general character above referred tor wherein the cradle slabbing-may be.y adjusted relative to the tank portions to compensate for shrinkage of the slabbing, thereby to cause the cradle portions to bear the weight of the tank portions to ythe desired extent, and be held in suoli adjusted position. i n

Referring to the accompanying drawings:

Inasmuch as II havedevised, my invention for use more particularly in connection with type with the ends'ofthe tank supported in a inannerto permit them to move. lengthwise of the car inthe expanding andl contracting of the tank, though not to the *exclusion of its use in connection with car'constructions wherein means of-other constructions and otherwise located, for-preventing displacement of the tank portions thereof lengthwise of the cars are provided, I have shown it as embodied in a tank car of the type above referred to, a tank car oic this general type being represented in Fig. l,

the tank being represented atr 20, the longitudinally-extendi-ng center sill of theV under frame at 21, the body kholsters at 22, and the center anchorage at 23. The particular anchorage means 'shown comprises the members 24 whichextendlengthwise yof the car structure, these members. being secured at and'being provided with tank-seating portions'26 and dependinglanges 27, the mem-v bers 24 being connected, las bythe rivets 28,

with the ldepending flanges 29 of angle bars 30 rigidly secured to the bottom wall of the tank 23 as through the medium of the rivets 31.

lhorizontal vflanges 25 to the center s ill 2l s ln accordance with common practice the ends of the tank 2O are supported to relieve 'the anchorage 23 of at least the major portion of the weight of the tank 20, while permitting the ends of the tank to shift in expanding and contracting, these means being in the form of cradles the upper portions of which are in the form of slabbing and upon which the end portions of the tank rest.

Referring now .more particularly to the construction shown in Figs. 2, 3, 4, 8, 9 and 10, this structure is illustrative of one embodiment of my invention as applied to bolsters of the so-called diaphragm, or pan, type wherein the. body bolster is formed of an upper, substantially horizontal plate-like member extending across the center sill 21, a lower plate-like portion 33 extending across the under side of the sill 21, and intermediate, or web, members 34, the members 32, 33 and 34, together with the sill 21,-be ing rigidly riveted together all in accordance with common practice. The cradle means carried by the bolster are shown as formed of members 35 having plate-like portions 36 each containing along opposite edges and an end thereof series of rivet-receiving apertures 37, 38 and 39 and containing along its center line at the end thereof' opposite that containing openings 38, a series of elongated slots 40. The member 35 is also formed with an `upwardly-extending flange 41 extending crosswise of the plate portion 36 and reenforced with webs 42, the liange 41 containing apertures 43 extending lengthwise of the members 35. The members 35 are positioned on the upper plate portions 32 of the bolsters 22 and are securely riveted thereto by rivets located in the openings 37, 38 and 39 engaging the underlying portions of the bolsters 22, the members 35 extending lengthwise of the holsters and extending at opposite sides of the center sill 21, the members 35 for each bolster being reversely positioned as shown in Figs. 2 and 3, whereby their hanged portions 41 extend adjacent the center sill 21. The' rivets which are located in the openings 3'? and 39 of the members 35 are countersunk to extend Hush withv the upper surfaces of these members which latter form bearing plates for members 44 which carry the slabbing represented at 45, and are adjustablel on the members 35 in a direction crosswise of the tank. The members 44 are shown as castings provided with depending lugs 46 which extend into the slots 40 and which while serving to prevent movement of the members 44 in a directionlengthwise of the car structure, permit of the adjustment of the latter crosswise thereof. The upper surfaces of the members 44 at which the slabbing 45 is supported, are preferably generally inclined as shown, and formed with grooves 47 extending lengthwise of the tankl and in which the slabbing is positioned, the latter being held in place as by means of the bolts represented at 48.

ln accordance with the illustrated preferred embodiment of my invention I provide the bolts 49 which extend through Openings in the members 44 and through the openings 43 in the members 35 and engage at their head and nut portions 50 and 51, respectively, with the flange 41 and the outer surfaces of the members 44these bolts serving as means for adjusting the members 44 toward the center line of the tank, and holding them in adjusted position.

In the arrangement shown in Figs. 5, 6 and 7 the invention is applied vto a construction of body bolster involving skeleton castings at its opposite ends which form the upper portions and the vertically-disposed web portions of the bolster, these castings being represented at 52 and forming with the sill 22 and the member 53 extending across the under side of the sill 22, the

bolster construction, the members 52 and 53 being riveted together and to the sill 22 as shown. In this particular construction the upper portion of each member 52 is of the same construction as the member 35 of the preceding figures, corresponding numerals being applied thereto in the drawings, except that the rows of rivet holes 37 and 39 shown in Fig. 8 are omitted, and instead of providing two of the slots 40 as' shown in Figs. 8 and 10, four of these slots are 100 the members 52 and are of the same con- 105 struction as the members 44 except that instead of providing two of the depending lugs shown at 46 in Figs. 9 and 10, four of" these lugs are provided so positioned as to extend into the slots above referred to in 110 the members 52 and cooperate therewith in the same way, and for the same purpose as the lugs 46 cooperate with the slots 40 in Figs. 8, 9 and 10, it being understood that the members 54 which carry the slab- -ll bing 45, are adjustable crosswise of the tank of the car for the purpose hereinbefore explained of the members 44, the construction now being described also involving the use of the bolts 49 cooperating with the 120 members 52 and 54 as stated of the previously-described construction.

The structure is also, and by preference, provided with bolts 55 which extend through the slots hereinbefore referred to 125 as provided in the upper surfaces of the members 52, and upwardly through the hereinbefore described depending lugs carried by the members 54 and extending into these slots, these bolts forming means, in 130 addition tothe bolts 49, for holding they members 54 in adjusted position.

It will bel understood from the foregoing that should rthe cradle slabbing i5 shrink and thus draw away from the tank, with,

theresult koi? subjecting the tank anchorage to stresses which it is desirable be avoided, the adjustable members carrying the slabbing may be adjusted toward the center line of the tank to compensate for the shrinkage of the slabbing, and cause them to occupy such a position relative to the tank and the portions of the structure beneath these members, that the anchorage for the tank will be relieved oi those stresses to which it would be subjected were such adjustments not made. n

While I have illustrated and described certain forms in which my invention may be embodied, l do not wish to be understood as intending to limit it there-to, as the same may be variously modified and altered without departing` from the spirit of the invention, and the invention may be embodied in other forms, if desired.

What I claim as new, and desire to secure by Letters Patent, is:
